Which of the given statements are correct?

Options

  1. AEntropy of micellization is negative as a large number of molecules associate to form larger molecules
  2. BEntropy of micellization is positive due to the increased freedom of hydrophobic chain in the nonpolar interio
  3. CEnthalpy of micellization is often positive
  4. DThe micellization process is governed primarily by the entropy gain associated with it

Correct answer

D. The micellization process is governed primarily by the entropy gain associated with it

Step-by-step solution

S is positive for micellisation. H is generally positive and this is compensated by the large negative values of ( - T S )
